IMPROVEMENT IN EMBROIDERING ATTACHMENTS FOR SEWING-MACHINES.

Specification forming part of Letters Patent No. 1 52,248, dated June 23, 1874; application filed May 14, 1874.

To all whom it may concern:

Be it known that I, CHARLES H. PALMER, of the city, county, and State of New York, have invented an Embroidering Apparatus, which is attached to, and operated with, sewing machinery, the object of which is to interlock a heavy cmbroidering thread with the sewing thread in such a manner as to show embroidery on the upper side of the fabric, of which the following is a specification:

Figure 1 represents a vertical view, seen from the front. Fig. 2 is a plan view. Fig. 3 is a side view of the needle-bar and cam.

Like letters refer to like parts.

a is the needle-bar of a sewing-machine. I) is the foot-bar, with foot 0 attached; 6 e, horizontal bearings, projecting from c; f, vertical oscillating shaft, with horizontal arm or disk 9 on the lower end, to which the embroideringneedle h is hinged, and by which it is operated. i is a collar, aflixed on top of the shaft f, and

. to which is attached the positive cam m, formed by a wire staple, twisted sufliciently to produce oscillation, in which the head of the setscrew 1 (which holds the sewing-needle in the needle-bar) works up and down with the needlel bar, and by which operation the oscillation of shaft f is effected. l is a friction-spring, impinging upon shaft f. Needle h is hinged in such a manner that when it is thrown forward toward the sewing-needle s (when the sewingneedle is up) it comes in front of the sewingthread, and moves beyond the vertical line of motion of the sewingneedle 8, carrying the sewing-thread with it, to enable the sewingneedle to descend between the embroideringneedle and the embroideringthread it holds. The screw-head 1" within the cam on ascends about one-half its whole distance without producing any oscillation of shaft f,- then shaft fis thrown to the right, and needle h is thereby thrown forward. But when the sewing needle commences to descend, shaft f remains at rest for a moment, in order that the sewingneedle g may glide between needle h and its thread before needle h is thrown backward to the left, by which operation the embroiderin thread is interlocked with the sewing-thread on the upper surface of the fabric, thus producing an embroidered surface.

To enable the embroidering needle to pass back while the sewing-needle is in the fabric, it is hinged in such a manner as to move (caused by impinging against the sewing-needle) upon the oscillating arm 9, and is immediately extended again by the spring n. c is an eyelet, through which the slack is given out and taken up.

L claim- The twisted spiral guide or cam in, in combination with vertical shaft f, horizontal arm g, and needle h, operating, substantially as set forth, in connection with needles, as described.
